Genetics Flashcard

Front

What is Incomplete Dominance?

Back

A type of inheritance where two alleles blend together to form a new phenotype, resulting in a mix of traits.

Front

What is Co-Dominance?

Back

A type of inheritance where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

What is the function of a Punnett Square?

Back

A visual tool used to predict the possible results of a genetic cross.

Front

How many alleles do you inherit from each parent?

Back

You inherit 1 allele from each parent, making a total of 2 alleles for each gene.

Front

What does a genotype of RR indicate about gametes?

Back

All gametes will carry the R allele.

Front

What is a Purebred organism?

Back

An organism that has two identical alleles for a trait, such as RR or rr.

Front

What is a Hybrid organism?

Back

An organism that has two different alleles for a trait, such as Rr.

Front

What is a Heterozygous genotype?

Back

A genotype consisting of two different alleles for a particular gene, such as Rr.

Front

What is a Homozygous genotype?

Back

A genotype consisting of two identical alleles for a particular gene, such as RR or rr.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by its genotype.
